America's largest selling truck is not just the Ford F-150, but the F-150 with a 5-1'2' bed. If your plan is to order only 1 pair, order item "Bull Ring 4056 Ford Short Bed W/Router Bit" If you want to order all 4 (2 pair) order this item plus "Bull Ring 4056 Ford Short Bed W/Router Bit"to save a few dollars. For years this Ford model has not been available with pop out covers built into the rail cap over each of the 4 stake pockets. Well now Bull Ring has an excellent solution for that with the new Ford Shorty Bull Ring. For the installation we've developed a custom router bit that enables you to quickly and easily trim out the top plastic rail to a perfect match of the steel pocket underneath. The design of our router bit incorporates 4 roller bearings that run along the steel pocket as a guide and all without scratching or cutting the painted surface of the rail. Now you're ready to install the low profile Ford Shorty Bull Ring and may we say, this is the best looking Bull Ring design to date. And if your plans include a tonneau cover, Ford Shorty works seamlessly with that installation as well.
